' Composing Mechanism of Typographical Machines, of which the following is a specification.

The present invention relates to improve ments in the composing mechanism of typographical machines. Such a composing mechanism always consists of the three following elements or their respective equivalents:(a,) character finger keys arranged in the form known in the art as a keyboard; (6) organs generally arranged a row to be actuated by the said finger keys,

respectively, either directly or indirectly;

and (0) means connecting each character finger key to its respective organ. It "is' a matter of indifi'erence to the present invention what is the type of-the said organs.-

That may vary to any extent with the type of machine. For instance, the organs may be escapements controlling matrices as in the composing-mechanism of the Mergenthaler line-casting machine, or punches punching holes in a mechanical controller as in the composing mechanism of machines known commercially under the trade mark Monotype. The application of the invention to the composing mechanism of a Mergenthaler line-casting machine has been chosen for the purpose of this specification. Such a machine is characterized by loose matrices stored according to their respective characters A, a, B, b, 1, 2, et cetera, in channels in a magazine, from which channels they are liberated, one at a time, in the order of composition, .by an escapement mechanism situated along the delivery mouth of the magazine and which is worked from a keyboard similar to that of a typewriter. As the matrices escape from the magazine, they are assembled in a com posed line which corresponds exactly with the intended line of print; The cdmposed line of matrices is then presented by the machine to its casting mechanism which pro ceeds to oast a bar of type metal s long as the intended line of print and aving in relief on one of its long edges, '6 characters properly spaced out into words to print that intended line. As soon as this-bar has been cast, the composed lineof matrices is distributed, each of its matrices being returned by the machine to the particular channel from which it was liberated, but into the end of it opposite to that from which it was liberated. Such a machine has been made capable of carrying two fonts of matrices difi'ering from each other in style of character or face," (to use the technical term), by adding a second magazine equipped with the additional font, the two magazines being parallel with each other and one above the other. Obviously, the operator could not ever be called upon to compose from both magazines, 2'. e., in both faces, at one and the same moment of time," although it is just possible that he might be called upon to change face immediately after he had liberated only one matrix in the preceding face, so that the addition of the second magazine did not necessitate the addition of a second keyboard, provided that a switch was introduced between the keyboard on the one hand and the two sets of matrix escapements one seton each magazine) on the other. There are as many character finger keys on the keyboard as there are matrix escapements in a set. These keys cooperate with the escapements of the set on to which the switch had switched them.

Referring to the drawings: Figure 1 is a transverse vertical section of a portion of a linotype machine, illustrating more particularly the escapement and keyboard mechanism. Figs. 2 and 3 are, jointly, a similar view showing one modification of, the present invention; Fig. 4 is a perspective view showing thecotiperation of a pair of finger keys with the respective pair of escapement rods; Fig. 5 is a plan of the keyboard; Fig. 6 is a vertical sectional view of av second modification; Fig. 7 is a similar view illus trating' a third modification; Fig. 8 is a similar view of a fourth modification; Fig. 9 is a detail view of a portion thereof: and Fig. 10 is a plan thereof. Referring to Fig. 1, 1,- 1, are two of the matrices in their respective channels 2; 2, of the magazine 3; and 4:. 4, two of the matrices in their respective channel 5, 5, of the magazine 6, all the matrices in each channel having the same character. One

magazine, say 3, is equipped with matrices having one style of character, say thick lined, while the other magazine 6 is equipped with matrices having another style, say thin lined. Further, each matrix has its own character in duplicate, say roman and italic. There are 90 channels in each magazine, but although the two magazines 3, 6, are equipped with two styles of character, each style in duplicate, making in all four varieties of character, the machine would have a font of only (say) 90 characters, because although the operator has a choice of four varieties of character, this choice of variety leaves the inclusiveness of the font limited to that number of characters. Both magazines are flat, the channels in each standing behind each other looking at Fig. 1. They are oblique in order that the matrices may slide along the respective channels by gravity. Each channel 2, 2, of magazine 3,-has its own escapement lever 7 fulcrumed at 8 on the magazine. 9 is a spring making a lever 7 hold a pawl 10 in engagement with the leading matrix 1, z. e., the one nearest the delivery mouth 11 of the magazine. A pawl 10 is held in that position by an escapement rod 12 pulled down by a spring 13. If the rod 12 were pushed up, the respective pawl 10 would be moved out of engagement with the said leading matrix 1, thereby liberating it, whereupon it would drop through the mouth 11 on its way to the assembling mechanism. The withdrawal of the pawl 10 would be accompanied by the engagement of the pawl 14' with the next matrix 1. When the spring 13 is allowed to pull the rod 12 down again, the said next matrix I would slide down a short distance only however to be engaged by the pawl 10. So that a reciprocation of the rod 12 means the liberation of the leading matrix 1 from the respective channel 2, 2. Each channel 5, 5, of the magazine 6, has likewise its own escapement lever 16 fulcrumed at 17 on the magazine, its spring 18, its pawls 19, 20, and a link 21 from a lever 16 to the respective escapement rod 22 which is pulled down by a spring 23 or a spring 23. A rod 22 stands edge on substantially opposite a rod 12. Each of the two magazines 3, 6, has its own font complete in itself, each font difiering from the other, and only one magazine can be composed from at a time. although each of the matrix channels 2, 2;

5, .5; in the magazines 3, 6, has its own escapement lever 7 or 16 and its own escapement rod 12 or 22, there are only half as many character finger keys 24 on the keyboard as there are matrix channels in both magazines. Each key 24 is fulcrumed at 25 and has its inner end loosely engaged with a vertically sliding bar 26 whose top end is loosely engaged with the horizontal Consequently,

arm of a bent lever 27 turning on a fixed fulcrum 28 and supporting by its upstanding arm, the free end of a lever 29 turning on a fixed fulcrum 30. A. lever 29 has a cam 31 rotatable in a slot 32 therein about a pivot 33. There is a set of parts 27 to 33 inclusive for each bar 26, and as these bars 26 are thin and must be close together, room for the said set of parts is found by placing one half of it in front of the row of bars 26 and the other half behind it. 34 is a roller extending under each half set of cams 31 at a short distance below it, both rollers being kept constantly rotating by the machine. 35 is a vertically sliding bar resting by its bottom end upon one of the inner ends of two levers 29 that are opposite each other, and holding its top end under, but at a short distance below, the plane of the bottom end of the respective escapement rod 12 or 22. There is a bar 35 for each pair of such escapement rods. The bottom ends of both rows of escapement rods 12 and 22, are embraced by a loop 36 connected to a bell-crank lever 37 turnable by the operator on a fixed fulcrum 38, far enough in either direction to move the bottom ends of one row of escapement rods 12 or 22 away from over, or into position over, the row of rods 35. The depression of a key 24, raises the respective bar 26 thereby making it raise the respective lever 27 far enough to place its upstanding arm under the respective slot 32 in the respective lever 29, whereupon the latter drops until its cam 31 rests upon the respective roller 34. The respective cam 31 is then rotated once, its longer radius rocking the free end of the respective lever 29 upward and making it raise the escapement rod 12 or 22 as the case may be. At the moment when a cam 31 completes its single revolution, its bent lever 27 enga es under the inner end of its lever 29, there y holding it ofi" the roller 34 and the cam itself is automatically stopped. Thus the combination of parts 27 to 33 with the respective roller 34, constitutes a power-driven mechanical relay capable of working the escapement mechanisms, the superior strength of such relay (because it is power-driven) allowing of each depression of a key 24 being effected by only a light touch on the part of the operator, While the combination of the row of bars 35, loop 36, and lever 37 is a manual shift between the keyboard on the-one hand and either of the two fonts of matrices in the respective magazines 3 or 6, on the other. The switch loop 36 and its lever 37 of the composing mechanism just described, although near the keyboard, are distinct from it and do not act on the set of bars 35 through any of the means by which the keys 24: act on them. Further, the said lever requires considerably more power to work than. does any key 24 to de- Ill the following claims.

press it. This requiring more power than a key 24, is true of every switch lever which it has been proposed to combine with the composing mechanism of a typographical machine. The present invention consists firstly, in each character finger key being capable of working its own shift; secondly, in a shift being worked by the same light touch that sufiices to depress a character finger key; thirdly, in a pair of organs being controlled by the corresponding pair of c aracter finger keys, acting through a single intermediate mechanism; fourthly, in two character finger keys of a pair being capable of actuating the two organs of a pair; each character finger key of a pair es.- tablishing conditions making it operative and the other key of thesame pair inoperative; and fifthly, in means for respectively effecting the said four results. Vi e believe ourselves to be the first to conceive the possibility of achieving the said results, and the first to invent means for accomplishing them. All these, both results and means, will now be described, and then defined in F igs. 2 to 10 illustrate four modifications of the invention, each of which is characterized by the three features above mentioned. Only two magazines 40, 41, are shown to facilitate comparison of the present invention with Fig. 1, but it must be distinctly understood that the said invention is not limited to this number. They may be either superposed as shown in Fig. 2, or be side by side in the same plane. Each may be equipped with its own font complete in itself, or the two (or any two or more if there are more than two) may be provided wlth any desired arrangement of characters,

as will be familiar to those skilled in the art.

The keyboard has as many character fin ger keys" as the magazines 40 and 41 have matrix channels 43, 43, for the -matrices 44, 44. Each matrix may have, as shown in F ig..2, two different characters 45. 46. The combination of escapement levers, springs, pawls, escapement rods, bent levers 27, 1e vers 29, cams and rollers 34, is the same as that described w th reference to Fig. 1, and the several parts of item therefore marked with the same reference numbers, respectively. Two character finger keys, adjacent in a front to rear sense. such as 47. 48 Figs. 4, 5), are on the same pivot 49, and both their inner ends 50, 51, engage in a slot .12

in a vertically sliding bar 53 which must be raised for the same purpose as a bar 26 in Fig. 1, by the depression of either finger key 47 or 48. The tops of the two ends 50, 51, are normally in touch with the top of the slot 52, and the latter is deep enough, in a vertical sense, to prevent the end of one fin ger key being raised by a rise of the bar 53 efiected by a rise of the end of the other finger key. A bar 53 has clipped 'to one side of it, so as to slide vertically thereon, a plate 54, and a similar plate 55 to the other side of it. Each plate 54, 55, has respectively a nose 56, 57, bent across the front edge of the bar 53 far enough to be enga ed by the respective end 50 or 51, but not arther than that, and a rearward projection 58, 59, which rests upon a fixed stop bar when the corresponding nose 56 or 57 rests upon the respective end 50 or 51. These two plates 54, 55, together constitute a selecting device. 61 is a bar holding its top end in touch with or within reach of the bottom ends of the two escapement rods 12, 22, and having a vertical slot 62 which is passed over a fixed transverse rod 63, the latter supporting the bar 61 so as to allow it to work with a reciprocating rocking motion from one escapement bar 12 or 22 to the other one, and also with a rising and falling motion in the plane of the respective two escapement rods 12, 22, and the inner end of the respective lever 29. A bar 61 receives its rising and falling motion from this lever 29, and its reciprocating rocking motion from opposite inclines 64, 65, on the respective tops of plates 54, 55, and which inclines engage under pins 66, 67 projecting laterally from the bottom corners of a plate 68, pivoted on the rod 63 and clipped to a bar I 61. This clipping is a loose one so as not to interfere with the above mentioned rising and falling motion. of a bar 61. According to Fig. 4, the finger key 48 operates escapement rod 12 and the finger key 47, the escapement rod 22. To allow them to act in this way, the incline 64 is downward to the rear and the cotiperating pin 66 is at the rear corner of plate 68, while the incline is downward to the front and the cotiperating pin 67 is at the front corner of plate 68. The bottom ends of the escapement rods 12, 22, and both ends of a bar 61 are so shaped as to enabie them to properly engage with each other, and a bar 61 with ,a lever 29. in view of the said rocking. The modification just described acts as follows: Let it be assumed that a matrix 44 from a channel 43 in the divisional magazine 40 is to be composed into the line. .The corresponding finger key 48 is depressed. Its rear end '51-.raises the bar 53, thereby rocking its bent lever 27 and allowing its cam 31 to drop on to the roller 34. One rotation of this roller rocks the inner end of the respective lever 29 upward far enough to make the bar 61 push up the esca ement rod l2 and make it leave the escapement lever 7 free to be. rocked by its spring 9 to free the leading matrix 44 in the channel 43 of the magazine 40, which channel is the one that is controlled by the finger key 48. But the end 51 engages the the 57 just before it engages the bar 53, makes it slide up the bar 53, engage the pin 67 and rock the plate 68 backward, such rocking motion of the plate 68 rocking the bar 61 out of engagement with the escapement rod 22 (dotted line position in Fig. 4) and into engagement with the escapement rod 12 (full lineposition in Fig. 4) before the above described action of the roller 34 makes the bar 61'push up the escapement rod 12. When the operator takes his finger off the finger key 48, the escapement rod 12 is pulled down by its spring 13, the bar 61 drops through the plate 68, the plate 55 drops till its projection 59 rests upon the stop bar 60 and the bar 53 drops with the end 51 of the said finger key, but the plate 68 is not rocked back-it retains the position into which it was rocked bythe'above mentioned depression of the finger key 48, viz :the full line position in Fig. 4. If the next matrix to be composed into the.line is one 44 from the same channel 43, the same finger key 48 is depressed, and the movements just described are repeated excepting the rocking of the plate 68 which rocking is unnecessary for the reason'stated. When a matrix 44 from a channel-43 in the magazine 41 is to be composed into the line, the operator depresses the finger key 47, which depression, acting through the parts 53, 27, 29, 31, 34 and 61 common to both finger keys 48 and 47, and also through the parts 56 and '66, which cotiperate with the finger key 47 only, rocks the bar 61 out of engagement with the escapement rod 12 and into engagement with the escapement rod 22, whereby the latter and the link 21 with it, are pushed up, the escapement lever 16 being thereby left free to be rocked by its spring 18 to free the leading matrix 44 in the said channel 43 which is the one that is controlled by the finger key 47. The removal of the operators finger from the finger key 47 is followed by a like return of the pants to that described with reference to the finger key 48. Likewise, the movements just described with reference to the finger key 47 will be repeated if the next matrix to be composed into the line is one 44 from the same channel 43*. It is now obvious from the foregoing description of this first modification of the invention that the described combination of plates 54, 55; bar 61; pivot 63; inclines 64, 65; pins 66, 67; and plate 68, constitutes a shift capable of being worked'by its co'tiperating character finger key or by either of its coiiperating character finger keys.

Second modification, (Figs. 5 and 6.) The two finger keys 70, 71, chosen for the purpose of describing this modification are in the ninth and tenth horizontal row, but they have the same relationship to each other as the two finger keys 47, 48, in that they are both in the same vertical row and control respectively matrix channels which are in the same vertical plane. Their inner ends 72 (only one shows in Fig. 6 because the other is immediately behind it) engage in a notch in the respective bar 53 as in the first modification. 73 is a vertically sliding plate on each side of a bar 53 having a front lug 74 bent around the front edge of a bar 53 above an end 72 so that when either end 72 raises a bar 53, it will also raise the respective plate 73. 75 is an upstanding bent lever fulcrumed on a transverse rod 78 fixed behind a row of bars 53 and its plates 73; and 77 is an upstanding bent lever fulcrumed on a transverse rod 76 fixed in front of the said row. The upstanding arms of a pair of levers 75, 77, are on opposite sides of the bottom end of the respective bar 61. A pin 79 projects laterally from each side of this bar into the path of the respective upstanding arm or lever 7 5, 7 7 so that when either finger key or 71, is depressed, the rise of its inner end 72 will make the respective bar 53, acting through the.respective lever 29, raise the respective bar 61; but before that bar, is so raised, the respective plate 73 will have rocked the respective lever or 77 to the front or rear, as the case may be,-and made it rock the top end of the bar 61 out of engagement with one escapement rod and into engagement with the other. In all other respects this second modification is the same as the first one, any two levers 7 5, 77 together constituting a selecting device.

Third modification, (Fig. 7 .)-This modification differs from the second one in dispensing with the row of bars 61, and substituting for them an upstanding arm 80 pivoted at 81 on the inner end of each lever 29 and having a pin 82 projecting from each of its (the arms) sides in the path of the upstanding arms of both the respective levers 75, 77, so that when either finger key 70 or 71 is depressed, the rise of its inner end 72 will make the bar 53, acting through the respective lever 29, push up the escapement rod 12 or 22, whichever the arm 80 is in engagement with; but before that escapement rod is so pushed up, the rise of the respective plate 73 will have rocked the arm 80 into engagement with the escapement rod 12 or 22 which corresponds with the depressed key 7 0 or 71. -It is any two levers 5, 77 that constitute a selecting devlce.

Fourth modificatz'on, (Figs. 8 to 10.) The two rows of the escapement rods 12, 22, have their bottom ends 83 cranked toward each other so as to form but one row. The inner end of each lever 29 has a cross head 84 pivoted to it by a vertical pivot 85 in order that the said cross head may be rocked out of engagement with the respective escapement rod 12 into engagement with the respective escapement rod 22 and vice versa. Each cross head 84, preferably the inner end of it, is embraced by an upstanding fork 86 sembler.

(Fig. 9) pivoted on a stationary pin, 87. Each bar 53 has a vertically sliding plate 88 on one side of it and a similar plate 89 on the other side of it, both plates being clipped to it so as to slide smoothly thereon, any two plates 88, 89, together constituting a selecting device. The respective pair of finger keys 47, 48, or 70, 71, have their inner ends connected with the respective bar 53 and its pair of plates 88, 89, in the same way as in the other modifications. The pair of plates 88, 89, carry their tops normally just underneath the bottom end of the respective fork 86, one top on each side of the respective pivot pin 87, so that when either finger key of apair is depressed, the rise of its inner end will make the respective bar 53, acting through the respective lever 29, push up an escapement rod 12 or 22 according as to which of these two rods the cross head 84 on the said lever 29 is in engagement with. This engagement is selected by the depressed finger key before the said lever 29 has be gun to push up an escapement rod, and the selection is made by the inner end of the depressed finger key raising the respective plate 88 or 89 and making it rock the fork 86 thereby carrying the respective cross head 8st under the escapement rod 12 or 22 whichever corresponds with the said finger key.

As the matrices issue from their respective divisional magazine 41, they pass through respective channels 90, 91, 92, into the part of the machine Which is known as the as- This part is Well known in the art, and, consequently, forms no part of the present invention. The matrices issuing, in the order of composition, from the bottoms of the channels 92, are assembled, side by side, in the assembler. All the matrices whose characters 4.6 are to be in the composed line, stand on one level, while all those whose characters are to be in that line, are automatically raised as they enter the assembler, to make them present their characters 45 in that line, and are automatically supported in that raised position. a

It frequently happens in the. use of a machine of the type described, that the operator will find himself called upon to compose in characters larger or smaller than those on the matricesin the magazine 40, 41, then on the machine. To meet this requirement, he takes the magazine 40, 41, with the matrices in it, then on the machine, ofi the machine and puts another magazine contain.- ing matrices having characters of the desired size, on it. But the downward pull of the rows of springs 13, 23, upon the rows of escapement rods 12 and 22, is too strong to allow of the two rows of escapement-levers 7 16, being disengaged from the respective rows of escapement rods 12 and links 21. To temporarily disengage them, there is a row of notches 94 in the frontface of the row of rods 22 and a like row of notches 95 in the rear face of the row of rods 12. A

rod 96 is mounted to turn in bearings in the frame of the machine opposite each row of notches 9st, 95, and parallel therewith. The right hand ends, looking at the machine from the front, of these rods, are geared together by segments 97, 97, and one of the rods carries a spring plunger handle 98 capable of moving over a fixed quadrant 99 and of automatically engaging by its plunger with a stop 100 at each end of the said quadrant. Each rod 96 is, for a length extending across the respective row of escapement rods 12 or 22, of any section that will enable it to present a shoulder 101 to the tops of the respective row of notches 94, 95, and raise the two rows of escapement rods 12, 22, to relieve the two rows of escapement levers 7, 16, from the pull of the rows of springs 13, 23, when the handle 98 is turned in the corresponding direction prior to the magazine 40, 41, being taken off the machine, and to allow the said springs to place both rows of escapement levers 7, 16, under the pull of those springs, after the substitute magazine has been placed upon the machine.
